Daeryun, Having Captured 'AI and Global,' Races Onto the World Stage With Accountable Litigation and Legal Tech Innovation [2026 Taxpayer Rights Grand Prize]

Daeryun LLC (representative attorney Kim Kook-il) won the 'Taxpayer Rights Grand Prize' for its contribution to protecting taxpayers' rights at the '2026 Tax Payment Grand Prize award ceremony' held at the Convention Hall of the Eliana Hotel in Seoul on the 25th.

The Taxpayer Rights Grand Prize was awarded to one corporation and two individuals who ordinarily contributed to protecting taxpayers' rights and to the development of the tax system. This ceremony was organized by Joseilbo and co-hosted by four academic societies: the Korean Accounting Association for taxation (inc.), the Korea Tax Policy Association (inc.), the Korea Tax Law Association (inc.), and the International Fiscal Association Korea (inc.).

Daeryun LLC recorded a double-digit growth rate last year, ranking 9th in revenue for two consecutive years. Daeryun's such steep growth is assessed as the result of the internal system reorganization and infrastructure investment it has continuously carried out.

According to the National Tax Service, Daeryun's revenue based on its 2025 value-added tax filing was about 130 billion won, a 15.4% increase from the previous year's revenue of about 112.6 billion won. The revenue growth margin was the second highest among major domestic law firms, after Shin & Kim (18.0%).

In addition, 'revenue per attorney,' assessed as a key indicator of sound management, was recorded at about 540 million won. This is at the level of 8th place, one notch higher than the overall revenue ranking, analyzed as the result of securing both efficiency of case handling and profitability.

Daeryun plans to firmly consolidate its position as a large law firm this year by focusing on sound management that enhances profitability and work efficiency, beyond mere outward expansion.

■ "Customer satisfaction is the top priority"…Introducing the litigation quality guarantee system and legal tech innovation

Daeryun laid a foundation for growth by building an accountable litigation system and introducing the industry's first litigation quality guarantee system. It built an accountable litigation system in which senior division-head-level attorneys oversee overall practice—client communication, strategy formulation, and court attendance—thereby preemptively resolving the service imbalance issue that can arise when junior attorneys are solely responsible for cases.

Next, another growth factor is that, to prevent the chronic consumer disputes in the legal service market, it introduced the industry's first 'litigation quality guarantee system.' It has codified a framework that refunds fees when service standards are not met, and immediately sends the real name and direct contact of the assigned attorney to the client right after retention, blocking any absence of communication at the source.

On top of this, it established a 'Time-Charge' settlement standard based on the actual work hours put into a case and the attorney's grade, and raised operational transparency by simplifying the complaint-handling process through a dedicated customer management center.

Building its own legal tech ecosystem to maximize internal work efficiency is also cited as a growth factor. To prevent the data-leakage risk of concern when relying on external platforms, it built its own technology infrastructure.

Through 'AI Daeryun,' a customized artificial intelligence trained by deep learning on tens of thousands of winning cases and litigation data, it dramatically improved the efficiency of issue extraction and precedent searches. It also links 'Romance-Law,' an internal solution equipped with an AI assistant, with 'My Daeryun,' a client-only communication application, to transparently share case progress with clients.

■ Leading a U.S. federal court lawsuit against Coupang…proving cross-border advisory capability

Cross-border legal advisory capability spanning borders is also cited as a major growth driver for Daeryun.

It built a 'two-way one-stop collaboration system' with the partner firm SJKP located in New York, U.S., helping domestic companies with corporate establishment and tax risk checks when entering the U.S., and conversely providing a customized package for U.S. companies to settle in Korea.

In particular, it operates a global complex crisis response TF, presenting locally embedded strategies that go beyond simple advisory to encompass actual dispute resolution such as restructuring and bankruptcy. Recently, it substantively proved its global crisis response capability by directly leading a class action against Coupang's U.S. headquarters in a U.S. federal court.

Based on such a systematic framework, Daeryun handles 15,000 to over 20,000 cases annually. It plans to leverage its know-how in the U.S. market as a springboard to swiftly pursue entry into global core hub cities such as Tokyo, Shanghai, and London, leaping to become a global law firm that provides uniformly high-quality legal services anywhere in the world.

Daeryun's representative Kim Kook-il explained, "Since consumers' expectations have risen, only by thinking of going all in for the customer can the chronic problems of the legal service market be solved," adding, "We will thoroughly manage things so that the quality of service customers feel improves, by expanding the legal tech and litigation quality guarantee systems."
